Assign issue type scheme to "next gen" projects

Hi!

Here is the API documentation for associating issue types with projects:
https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-type-schemes/#api-rest-api-3-issuetypescheme-project-put
It says that

Issue type schemes can only be assigned to classic projects.

Now how can I assign issue type schemes to “next gen” projects via API?

Thank you for your answers in advance!

When did Next Gen (Team Managed) projects start supporting issue type schemes ???

Hi! @sunnyape! I just want to add a new issue type for the “next gen” project whatever way it is possible. I want this “Add issue type” function to work with the REST API.

Sorry, but you initially said you wanted to create an Issue Type SCHEME, but now you’re asking about how to create an Issue TYPE, and they are not the same thing.

It is currently not possible to create Issue Types for Team Managed projects using Jira’s REST API.

Just Google ‘jira rest api create team managed project issue type’ and you’ll find where your question has been answered in threads such as this one, and also be lead to the matching feature request JSWCLOUD-23545

So you are saying that there are no possible way that we can add Issue Types to Next gen projects via REST API now?
